摘要
运用区域重心、地理集中度及不一致指数等模型,对环洱海地区1988年~2012年耕地与农业劳动力的空间分布与耦合关系进行分析。得出以下结论:随时间演进,耕地重心呈向西北为主、东南为辅的变动态势,而农业劳动力重心的阶段性变动明显,整体向西南偏移;25年间,耕地与农业劳动力重心的空间重叠性与变动一致性均大幅提高,两重心耦合态势日趋明显。海西地区耕地与农业劳动力地理集中度均远高于海东,洱海西岸、S221及G214沿线分别为耕地与农业劳动力的主次要集聚轴;自1988年以来,耕地向海西中北部集聚,而农业劳动力呈现出由分散转为集中的布局态势,整体上两者呈高度正向相关性;随时间演进,村域耕地与农业劳动力空间分布的协调度明显下降,依据不一致指数,可分为耕地优势集聚型、农业劳动力分布滞后型、耕地—农业劳动力空间协调型、耕地分布滞后型及农业劳动力优势集聚型五类村庄。
Based on the models of regional gravity center, geographic concentration index and inconsistency index, from 1988 to 2012, the spatial distribution and coupling relationship between arable land and agricultural labor force in Erhai lake Area are analyzed. The results indicate that： with time going on, the evolutionary trend of the gravity center of arable land was mainly to the northwest, while southeast as a secondary; the phased change of the gravity center of agricultural labor force is obviously, overall shifted to the southwest; In 25 years, the space-overlaps and changes in consistency of arable land and agricultural labor force gravity were both significantly increased, the coupling trend of the two gravity centers are becoming more and more obvious. The degree of geography concentration of arable land and agricultural labor force in Haixi area are both far above those in Haidong, the west coast of Erhai Lake, S221 and G214 are the main and minor agglomeration axis of arable land and agricultural labor force respectively; Since 1988, the arable land gathered to the central and northern regions of Haixi, while the agricultural labor force showing a change from decentralized to centralized layout, as a whole, there was a highly positive correlation between them; With time going on, the coordination degree of spatial distribution of arable land and agricultural labor force in the village area decreased obviously, according to the inconsistency index, the Erhai lake Area can be divided into five types of villages which are arable land advantage agglomeration type, agricultural labor force lag distribution type, arable land-agricultural labor force spatial coordination type, arable land lag distribution type and agricultural labor force advantage agglomeration type.
